" eas- REGULATOR For. isUNsnN'BURNnns.A

To all whom "it may comer'n- A j Be it known that I, FRANK S.I)Annnn, a citizen of the United States, residing yat Meriden, county of New Haven, State of Connecticut, have invented certain' new and useful Improvements in Gas-Regulators for Bunsen Burners, of which the following is a full,-clear, and exact descript-ion.

My invention relates to a gas regulating device for Bunsen burners, the object of the invention .being to provide a simple Vand effective regulator mechanism whereby very -fine adjustment can be effected.

In the accompanying drawings Figure 1 1s a side elevation, relatlvely enlarged. Fig. 2 1s a vertlcal section showing the parts 1n one position. Fig. 3 is a similar View showing the parts in another position. Fig. 4 is a View `of the inner end of the manua lyoperable element dctachedxfrm .the bo y of the gas tip. Fig. 5 is a side elevation.l of

the valve detached.

-l is the main body of the gas tip, which is usually provided witl'rthe screw-threaded portion 2, onto which the Bunsen tube (not shown) may b". screwed. 3 is the usual internal screw-thread, by which the tip is secured tothe gas fixture.

4 is a small central outlet `for the gas in the top of the tip l.

Extending longitudinally in the body of the tip l is an enlarged valve receiving cavity, and arranged therein is a conical valve 5 having a relatively enlarged guide body portion (3, which 'may have any desired number of longitudinal clearance passages in its outer side to permit gas to iiow past said body towardthe outlet 4. The guide body G so lits the boreof the tip body 1 to properly center the point of the conical valve 5 with respect to the gas outlet 4. The lower end of the guide body 6 is slotted longitudinally, the bottomof the slot being formed on an incline, as shown at S is a nut preferably having a beveled incline to correspond with the bevel 7. This nut is cut away ou opposite sides, as best seen in Fig. 4, so thatit will stand in the4 slotted lower end of the guide body 6,` and not turn therein.

9 is the stem of a controlling device, pref erably fitted 4with a knul-led finger-piece 10 and having a. threaded forward end 11,upon which the nut 8 is mounted.

.tip body 1, said spring operating to push the valve 5 downwardly againstthe nut 8.

The ad justment'of the valve is effectedas follows: Rotation of the linger-piece 10 in the proper direction will" ca use the nut 8 to advance -on the thread l1. rl`he nut S moving against the incline 7 pushes the valve upwardly from the position shown in Fig. 2 toward the position shown in Fig.

3. This movement tends to reduce the size of the gas outlet 4. Reverse rotation of the linger-piece 10 moves'the nut in an. Opposite direction on the thread 11, whereupon the spring 15 operates to move the valve 5 back to its origina-1 position, said movement opening the gas outlet 4. It will be Observed that a substantial rotation of the finger-piece 10 imparts but relatively slight longitudi nal movement of the nut 8 on the screw 11, and hence since the incline 7 is what may be termed an easy incline, it follows that a substantial turn of the finger-piece 10 iinparts but very slight movement tothe valve l5. Accordingly it is possible to secure the most accurate adjustment by this very simple and relatively inexpensive means.

What I claim is:

1. In a gas regulator, a tip, a passage therethrough, a contracted gas outlet at one ,end thereof, a valve for said yas outlet longitudinally guided and movab e in said passage, a spring operating to move the valve in one direction, an incline on the valve, and a manually operable nut movable transversely of the valve and bearing 'against said incline .and arranged to move vice movabletransversely in said guide passage to move said valve in an op osite directlon, said device belng operative y connected with'said valve, the line of connection b eing obliqueor in'clined relatively to the dlrection of movement' of the movable device,

.said device being in the form of a non-rotatable nut with a. rotatablescrew-threaded .support therefor-the latter being arranged a. tapered valve mounted to slide in said v passage, the body portion of saidvalve being guided by the Walls, thereof, said body portion having a longitudinal s'lot, the end of said slot having an inclined'wall, a nut standing in said Slot and arranged to 'engage said incline, a screw-threaded rotatable mounting for Asaid nut whereby the latter may be moved toward andfrom said incline, and a'. spring acting on said valve .to'hold said incline against said nut.
